Brownie "Hamburgers"

Step 1
Preheat oven to 350 degrees F (175 degrees C). Grease two 9-inch square baking pans.

Step 2
Mix brownie mix, oil, eggs, and water together in a bowl until batter is smooth; spread into the prepared pans.

Step 3
Bake in the preheated oven until brownies are cooked through and edges are beginning to pull away from sides of pan, 20 to 25 minutes. Cool brownies.

Step 4
Cut cooled brownies with a shot glass or small cookie cutter so they are slightly larger than the vanilla wafer. Put a small dot of chocolate frosting on the bottom and top of each "burger".

Step 5
Make a rim around half of 60 vanilla wafer "top buns" with red gel representing the ketchup. Sandwich the "burger" with 2 vanilla wafers, with the "ketchup" wafers on top.
